Optimized Treatment and Heart Rate Reduction in Chronic Heart Failure
BACKGROUND Heart failure (HF) is a syndrome that leads to poor outcome in advanced forms. The neurohormonal blockade modifies this natural history; however, it is often suboptimal. OBJECTIVE The aim of this study is to assess at what percentage cardiologists used to treating HF can prescribe target doses of drugs of proven efficacy. METHODS A total of 104 outpatients with systolic dysfuncti...
متن کاملBenefit of Heart Rate Reduction in Heart Failure
Epidemiological studies have suggested that life expectancy is inversely related to resting heart rate and that the risks of development of heart failure and sudden cardiac death strongly increase with higher resting heart rates [1]. After myocardial infarction, the reduction in mortality with β-blocker treatment was correlated with the extent of heart rate reduction, and in patients with heart...
متن کاملResting heart rate rapid reduction by moderate exercise evolutionarily encoded
Background: Global physical inactivity pandemic is responsible for more than 5 million deaths annually through its effects on non-communicable diseases. This requires urgent intervention. Objective: To investigate associations of physical activity with cardiovascular fitness in a cross-sectional retrospective observational study. Data were collected for 21 years from 2530 healthy volunteers and...

متن کاملHeart rate reduction with ivabradine improves energy metabolism and mechanical function of isolated ischaemic rabbit heart.
AIMS The anti-anginal agent ivabradine slows heart rate (HR) by selectively inhibiting the I(f) current in the sinus node. We report an ex vivo study to evaluate the anti-ischaemic effect of ivabradine in terms of modulation of cardiac energy metabolism. METHODS AND RESULTS A Langendorff-perfused rabbit heart model was subjected to low-flow ischaemia and reperfusion. Cardiac metabolism was st...
